Hey there, well im servicing my bimmer on my own for the first time and i plan on getting K&N Air & Oil Filters, and Royal Purple Synthetic Oil, BUT i dont know how many quarts to get for my '97 528i. Please help and thank you.
Also what are ur guys expirience's with the products i plan on using?

I would not recommend the K&N air filter. It offers no performance benefit and may allow contaminents into the intake. The oiled air filter is somewhat cheesey. You will find many proponents of K&N air filters and many detractors. Do a search for more additional info. Most on this forum stick with Mann or Mahle oil filters. Again, for no performance gain, why bother to switch? RP is a highly recommended oil. The e39 M54 3.0 engine requires 6.5 qts of oil. The M52 should be similar. Do a search for more detailed model specific information.

Damn so even though it says its going to be the only air filter im going to need, its still not a good buy? Is it the same for the Oil Filter in ur opinion? And where can i get my hands on a Mann or Mahle Air Filter?

I have a '98 528. I pour in 7 qts of liquid gold (mobile 1), with a filter change. As for the K&N- Return it. The oiling is a pain, and if you get too much it has been know to foul up the MAF sensor. Too little and the dirt doesnt stick to it. You wont notice and performance difference either. A good source of BMW parts is http://www.pelicanparts.com/bmw/cata...eries_Main.htm and http://www.ecstuning.com/. There are lots of others, but I've been using these for years and always have great service.

The K&N or any other gauze and oil soaked filter is more for offroad use than street use.
And as what's said, too much oil used on the filter and oil residue falls out of suspension and travels down the intake track to coat your MAF & throttle body, two very important parts that needs to be absolutely clean to function properly.

While "lifetime" parts save you some money, there is a trade off. Only you can answer whether that trade off is worth the added risks. Most Festers tend to take the conservative approach and spend the money for the "right" parts.

While the K&N oil filter (or any other brand) might work fine, you will find that most 'Festers tend to use German parts or OEM equivalents. They are available at the various vendors that sponsor B'fest.
